Which type of tissue is characterized by cells found on the internal surface of the stomach, no extracellular matrix, tall and thin cells, and the absence of blood vessels?
Correct Answer: A
Rationale: The tissue described in the question, where cells are found on the internal surface of the stomach, are tall and thin, lack an extracellular matrix, and do not contain blood vessels, corresponds to epithelial tissue.

Question 4 of 5
What is the name of the structure that prevents food from entering the airway?
Correct Answer: D
Rationale: The structure that prevents food from entering the airway is the epiglottis. The epiglottis is a flap of cartilage located behind the tongue at the top of the larynx. During swallowing, the epiglottis covers the opening of the trachea, directing food and liquids to the esophagus instead of entering the airway. This mechanism ensures that food safely passes into the digestive system, avoiding any blockage of the respiratory pathway.
